- a predetermined film for example, a gate insulating film is formed on the substrate 10 by the CVD process (step 102).
- the substrate 10 is carried into the posture changing chamber 70 through the transfer chamber 53, and the posture of the substrate 10 is changed from the horizontal posture to the vertical posture (step 103).
- the substrate 10 in a vertical posture is carried into the sputtering chamber through the buffer chamber 63 and is transferred to the end of the first sputtering chamber 61 through the forward path 64. Thereafter, the substrate 10 passes through the return path 65, is stopped in the first sputtering chamber 61, and is subjected to the sputtering process as follows.

- FIG. 4 is a diagram showing a state of sputtering. Sputtering proceeds in the order of FIGS. 4 (A), (B), and (C).
- the magnet 83 is disposed at a first position that does not face the substrate 10.
- the sputtered region 80 a is generated in the vicinity of the magnet 83 on the sputtered surface of the target 80.
- the sputtered particles emitted from the region to be sputtered 80a are diffused at a certain angle and reach the surface to be processed of the substrate 10 to be deposited.
- the sputtered particles that reach the surface to be processed at this stage are sputtered particles emitted from the sputtered region 80a in an oblique direction with respect to the sputtered surface. Since the region to be sputtered 80a does not face the substrate 10, the sputtered particles emitted in the direction perpendicular to the surface to be sputtered do not reach the surface to be treated.
- the magnet 83 When film formation is performed with sputtered particles incident obliquely on a part of the surface to be processed of the substrate 10 that is close to the sputtered region 80a, the magnet 83 is driven by the driving mechanism, and the state shown in FIG. Move as shown. This movement causes the magnet 83 to move from a first position that does not face the substrate 10 to a second position that faces the substrate 10. Even during this movement, sputtering proceeds (an electric field and a magnetic field are applied). The sputtered region 80 a also moves on the sputtered surface together with the magnet 83 and takes a position facing the substrate 10.
- sputtered particles emitted in an oblique direction and a vertical direction with respect to the sputtered surface reach the processing surface of the substrate 10.
- a part of the sputtered particles emitted in the oblique direction reaches a (novel) region where the film is not formed on the surface to be processed.
- the sputtered particles emitted in the vertical direction reach the region where the film has already been formed in the previous stage shown in FIG.
- the magnet 83 When a film having a predetermined film thickness is formed by the sputtered particles emitted in the vertical direction, the magnet 83 is further moved as shown in FIG. 4B, and emitted in an oblique direction at the stage shown in FIG. 4B. The region formed by the sputtered particles is further formed by the sputtered particles emitted in the vertical direction. Thereafter, the magnet 83 moves in the same manner, and film formation proceeds over the entire region of the surface to be processed of the substrate 10. Although the movement of the magnet 83 is continuous, it may be stepwise (repeating progress and pause).
- the surface to be processed of the substrate 10 is first formed by the sputtered particles emitted in the oblique direction from the sputtered region 80a, and then formed by the sputtered particles emitted in the vertical direction.
- the number of sputtered particles emitted in an oblique direction reaches a unit area of the surface to be processed is smaller than that in the vertical direction. Thereby, the incident energy per unit area received by the surface to be processed is also reduced, and the damage received by the surface to be processed is small.
- the film forming speed is slow. However, the subsequent vertical sputtered particles can be formed without significantly reducing the overall film forming speed. Since the sputtered particles in the vertical direction reach only the region where the surface to be processed is already formed, the existing film serves as a buffer material and does not damage the surface to be processed.
- the substrate 10 on which the IGZO film is formed in the first sputtering chamber 61 is transferred to the second sputtering chamber 62 together with the support plate 91.
- a stopper layer made of, for example, a silicon oxide film is formed on the surface of the substrate 10 (step 104).
- the film formation process in the second sputter chamber 62 employs a fixed film formation method in which the substrate 10 is made to stand still in the second sputter chamber 62 in the same manner as the film formation process in the first sputter chamber 61.
- the present invention is not limited to this, and a passing film formation method in which the substrate 10 is formed in the process of passing through the second sputtering chamber 62 may be employed.
- the substrate 10 is carried into the posture changing chamber 70 through the buffer chamber 63, and the posture of the substrate 10 is changed from the vertical posture to the horizontal posture (step 105). Thereafter, the substrate 10 is unloaded outside the vacuum processing apparatus 100 via the transfer chamber 53 and the load lock chamber 51 (step 106).
- CVD film formation and sputter film formation can be performed consistently within one vacuum processing apparatus 100 without exposing the substrate 10 to the atmosphere. Thereby, productivity can be improved. Further, since moisture and dust in the atmosphere can be prevented from adhering to the substrate 10, it is possible to improve the film quality.
- the initial IGZO film with low incident energy, damage to the gate insulating film, which is the base layer, can be reduced, so that a field effect thin film transistor with high characteristics can be manufactured. it can.

Note that the magnet 283 may not be fixed to the backing plate 282, and the magnet 283 may be moved by a drive source different from the backing plate 282.
- the sputter cathode Td is moved in a direction parallel to the surface to be sputtered of the target plate 281 with respect to the substrate 210 by a driving mechanism (not shown).
- the sputter cathode Td takes a first position where the target plate 281 does not face the substrate 210 and a second position where the target plate 281 faces the substrate 210.
- the sputtering gas is turned into plasma by the applied electric and magnetic fields.

- the sputtering cathode Td exists at a position where the target plate 281 does not face the substrate 210. Therefore, among the sputtered particles emitted from the sputtered region 280a of the target plate 281, only those emitted in the oblique direction with respect to the sputtered surface reach the treated surface of the substrate 210 and are emitted in the vertical direction. Things do not reach the surface to be processed.

- ⁇ indicates the film thickness when the oxygen introduction amount is 1 sccm (partial pressure 0.004 Pa)
- ⁇ indicates the film thickness when the oxygen introduction amount is 5 sccm (partial pressure 0.02 Pa)
- ⁇ indicates The film thickness when the oxygen introduction amount is 25 sccm (partial pressure 0.08 Pa)
- ⁇ indicates the film thickness when the oxygen introduction amount is 50 sccm (partial pressure 0.14 Pa).
- the film thickness at point A where the sputtered particles emitted from the two sputter cathodes T1 and T2 reach is the largest, and the film thickness decreases as the distance from the point A increases.
- the point C is a deposition region of sputtered particles emitted obliquely from the sputter cathode T2, and thus has a smaller film thickness than the sputtered particle deposition region (point B) incident from the sputter cathode T2 in the vertical direction.
- the incident angle ⁇ of the sputtered particles at this point C was 72.39 ° as shown in FIG.
- FIG. 9 is a diagram showing the relationship between the introduced partial pressure and the film formation rate measured at points A, B and C. It was confirmed that the film formation rate decreased as the oxygen partial pressure (oxygen introduction amount) increased regardless of the film formation position.
- thin film transistors each having an active layer made of an IGZO film formed with different oxygen partial pressures were produced.
- the active layer was annealed by heating each transistor sample in air at 200 ° C. for 15 minutes.
- the on-current characteristic and the off-current characteristic were measured about each sample. The result is shown in FIG.
- the vertical axis represents on-current or off-current
- the horizontal axis represents oxygen partial pressure during the formation of the IGZO film.
- the transistor characteristics of a sample in which an IGZO film is formed by a pass film formation method by RF sputtering are also shown.
- ⁇ is the off current at point C
- ⁇ is the on current at point C
- ⁇ is the off current at point A
- ⁇ is the on current at point A
- ⁇ is the reference sample.
- the off current, “ ⁇ ”, is the on current of the reference sample.
- the on-current decreases as the oxygen partial pressure increases in each sample. This is presumably because the conductive properties of the active layer are lowered by the increase in the oxygen concentration in the film. Further, when the samples at point A and point C are compared, the sample at point A has a lower on-current than point C. This is thought to be due to the fact that the underlying film (gate insulating film) suffered significant damage due to collision with sputtered particles during the formation of the active layer (IGZO film), and the desired film quality of the underlying film could not be maintained. It is done. In addition, the sample at the point C had the same on-current characteristics as the reference sample.
- FIG. 11 shows experimental results obtained by measuring the on-current characteristics and off-current characteristics of the thin film transistor when the annealing conditions of the active layer are 400 ° C. for 15 minutes in the atmosphere. Under this annealing condition, there was no difference in on-current characteristics for each sample. However, regarding the off-current characteristics, it was confirmed that the sample at point A was higher than the sample at point C and each sample for reference. This is presumably because the base film was greatly damaged by collision with the sputtered particles during the formation of the active layer, and the desired insulating properties were lost.
- the active layer of the thin film transistor is formed by sputtering, the on-current is high and the off-current is low by forming the initial layer of the thin film with sputtered particles incident on the substrate from an oblique direction. Excellent transistor characteristics can be obtained.
- an active layer having an In—Ga—Zn—O-based composition having desired transistor characteristics can be stably manufactured.
- the method for manufacturing a thin film transistor using an IGZO film as an active layer has been described as an example.
- the present invention can also be applied to the case where another film forming material such as a metal material is formed by sputtering. is there.

スパッタの開始時点において、マグネット83は第1の位置に配置されている。第1の位置はマグネット83がターゲット80を介して基板10と対向しない位置、すなわちターゲット80の被スパッタ面のうち基板10と対向しない領域の背面に相当する。後述するが、スパッタが進行すると、マグネット83は駆動機構によって駆動され、基板10と対向する位置である第2の位置に移動する。 The arrangement relationship between the

スパッタは、図4(A)、(B)、(C)の順に進行する。図4(A)に示すスパッタの開始段階では、マグネット83は基板10と対向しない第1の位置に配置されている。被スパッタ領域80aはターゲット80の被スパッタ面のうち、マグネット83の近傍に発生する。被スパッタ領域80aから出射されたスパッタ粒子は、ある程度の角度を持って拡散して基板10の被処理面に到達し、堆積する。この段階で被処理面に到達するスパッタ粒子は、被スパッタ領域80aから、被スパッタ面に対して斜め方向に出射されたスパッタ粒子である。被スパッタ領域80aは基板10と対向していないため、被スパッタ面に対して垂直方向に出射されたスパッタ粒子は被処理面に到達しない。 FIG. 4 is a diagram showing a state of sputtering.
